    About the Role

    We’re seeking a Lead Software Architect with deep expertise in backend development and building scalable, high-performance systems. This role is perfect for someone who thrives in fast-paced, high-scale environments—where milliseconds matter—and can architect solutions capable of handling thousands of transactions per second with reliability and speed.

    Key Responsibilities

    • Architect and lead the design of scalable, high-availability microservices for payment and transaction systems.
    • Collaborate with engineering leads and DevOps teams to implement containerized solutions using Kubernetes.
    • Ensure robust performance in high-transaction environments, optimizing systems for speed and fault tolerance.
    • Drive full-stack architectural decisions, balancing backend performance with seamless user experiences.
    • Mentor development teams and enforce software engineering best practices.
    • Partner with stakeholders across security, product, and infrastructure to align system architecture with business goals.

    Technical Requirements

    • 8+ years of backend development experience with deep expertise in Java (Spring Boot, JDK 11+).
    • Proven track record of architecting and scaling systems in high-throughput environments (e.g., payment gateways, fintech, eCommerce).
    • Strong experience with Kubernetes, containerization, and cloud-native deployments (GCP, AWS, or Azure).
    • Solid understanding of microservice architectures, service mesh, and event-driven systems.
    • Familiarity with full-stack development—experience with modern front-end frameworks a plus.
    • Expertise in scaling distributed systems, managing load balancing, caching, and redundancy.

    Nice to Have

    • Experience with PCI compliance or secure payment systems.
    • Knowledge of real-time monitoring and observability tools (Prometheus, Grafana, ELK).
    • Prior work in scale-up or startup environments.
